The invention claimed is: 
     
       1. An antenna arrangement comprising a body comprising a plurality of antenna devices arranged in one row, the body having a flexible structure and an elongated shape and at least one of the antenna devices comprises an antenna pair arranged non-orthogonally in a co-polarizing manner. 
     
     
       2. The antenna arrangement according to  claim 1 , wherein each antenna pair is arranged non-orthogonally by being arranged at angles not being straight with relation to one another. 
     
     
       3. The antenna arrangement according to  claim 1 , wherein each antenna pair is arranged non-orthogonally by being at least one antenna of the antenna pair being arranged in a bent or not straight form. 
     
     
       4. The antenna arrangement according to  claim 1 , wherein the antenna arrangement comprises at least two antenna pairs, where the antenna pairs are arranged so that the polarity of one antenna pair is opposite the polarity of an adjacent antenna pair. 
     
     
       5. The antenna arrangement according to  claim 1 , further comprising a connector for connecting the antenna arrangement to a central unit, acting as a base station. 
     
     
       6. The antenna arrangement according to  claim 5 , further comprising a bus portion and a power supply line for transmitting data to and from the plurality of antenna devices and/or to/from the central unit. 
     
     
       7. The antenna arrangement according to  claim 6 , wherein the bus portion and the power supply line are the same connection. 
     
     
       8. The antenna arrangement according to  claim 1 , wherein each antenna device comprises a controller (CPU) and an antenna element (ANT), wherein said controller (CPU) is configured to perform per element processing, the antenna arrangement thus being arranged for distributed processing utilizing the controllers (CPU) of the antenna devices. 
     
     
       9. The antenna arrangement according to  claim 1 , further comprising or being arranged to be connected to a connector for connecting the antenna arrangement to at least one other antenna arrangement. 
     
     
       10. The antenna arrangement according to  claim 9 , further comprising or being arranged to be connected to a power unit. 
     
     
       11. The antenna arrangement according to  claim 1 , wherein at least a majority of the antenna devices are arranged to face the same direction. 
     
     
       12. The antenna arrangement according to  claim 1 , further comprising at least one additional device. 
     
     
       13. The antenna arrangement according to  claim 1 , wherein the antenna devices are arranged in a cover or sheath of said body. 
     
     
       14. The antenna arrangement according to  claim 1 , wherein the body is a cable. 
     
     
       15. The antenna arrangement according to  claim 1 , wherein the body is an elongated strip. 
     
     
       16. The antenna arrangement according to  claim 1 , wherein the body is a film. 
     
     
       17. A distributed massive MIMO (Multiple Input Multiple Output) system comprising a central unit arranged to act as a base station and at least one antenna arrangement comprising a plurality of antenna devices, the body having a flexible structure and an elongated shape and at least one of the antenna devices comprises an antenna pair arranged non-orthogonally in a co-polarizing manner. 
     
     
       18. The distributed massive MIMO system of  claim 17 , further comprising an antenna panel.
